' Thisinvention relates to improvements in the devices for the transfer or'carry-on'from. Jone registering drum .to' the next inj; cash v registers and otherinachines intended for "the mechanicaladding of either numerals ,or monetary unitsl. I

I- Theldevicesto 'be described' are only ,ap

-p'licable to a machine which requires aspevcial key-lever or one of a series U of v special 1 "key-levers to be depressed every timebefore the operation of any "one of theusual series of adding f key levers.

The {function ofthese specialkeysmxceptin sofar asthey [assist in; the operation of transfer, will not be referred to, as such, function is no partof thepresent application and as any one of these special keys-is sufficient for the trans- *fer, onlyzione of such keysiwill be; shown.

,The transfer'is effected by.:a spring-pulled v that there is, in additionto the strong pull compound'lever 'whichjg Withdrawn from Fig. 2 is aplanview of theuniversal. yoke.

, positions leaving however the transfer-lever depressed and ready to cause transfer whenever the pin 6 Fig. 4 on the first drum,

comesfinto contact with the point 62 of the lever detent 59-Fig. 1.- When this happens the slight displacement of the lever detent 59, first moves the spur 63 to disengagev the short rod 64, which releases the lever 65 to the action of the spring 45. When rocked to such position the face 90 of the detent 59 is arranged to form with the edge 71, of, the detent 68, apas'sage for the rod 64, which guides the point 47 of-the lever 65'into engagement with the pins 82 of the drum 74. The lever-detent 68, pulled upwardbyits spring 70,'rises-at the same time, the edge 71 still being in contact with the short rod 64, but when'the projection 72 of the leverd'etent 68, strikes the part 73,the upward movement of the, lever-detent 68 is arrested and the short 1'06. 64 frees itself from the the adjacent partition'58.

edge 71 and moves to the left. 47 of the transfer lever 65 also; moving to the left, contacts with one of thepins 82 and rotates the drum 74 through one unit.

For confining the movement of the detent 59, the same, may be formed with a slot 66 cooperating witha pin 67 projecting from In Fig.3 the transfer lever 65'is shown after it has; caused transfer, its 'point 47 is seen between two of the pins 82, and its movement tothe left has been checked by the rod It remains in this position until the next operation of the key 1; a

The objects of the lever-detent 68 in addition to holding the short rod 64 in a'depressed position are to reduce the force required for a series of transfers from drum to drum and also to cause the transfer-lever 65 to rise slightly before making any movement to the left, in. order that this movement may causethe rotationof the drum through one unit.

The

substitution of two straight, springs, 5 and e 5 secures greater precision in this alinement, whlch is necessary'to insure the accurate depression and unfailing detention of all or, V

any of the. transfer levers 65.

What I claim is V 1. In a mechanical adding machine, a dew vice for the transfer from one of a series'of registering drums to the next, comprising in combination a lever comprising a substantially vertlcal armand a lower arm at suba frame,,a link for said leverandpivote'd to said frame at oneend, pivot pin connect ing the other end of said link to said vertical arm of the lever, a stop onsaid frame adaptraise said yoke, and a key lever adapted when depressed to lower said yoke whereby as the lever is,,lowered by said yoke the upperend of the lever moves at first radially with respect to said registering drum and of rotation of said drums.

2. In a mechan cal adding machlne, a device forthe transfer from one of a seriesof stantially right angles to said vertical arm,

then rearwardly with; respect to the direction i registering drums to the next, comprising in a combination a compound spring-actuated transfer lever, a spring-actuated pivoted yoke, a key lever adapted to actuate said yoke against the influence of its springto retract said lever, an abutment projecting laterally from said lever, and 'of pivoted bar and cooperating spring-actuateddetent adapted toembra ce said abutment to hold said lever when retracted.

3. In a mechanical adding machine, adec vice for thetransfer from one of a series of registering drums to the next, comprising in combination a oompoundi spring-actuated transfer lever; a spring-actuated pivoted yoke, a key lever adapted to actuate said yoke, against the infiuence of its spring to i retract said lever, an abutment projecting 1 laterally from said lever, a pivoted bar and.

cooperating spring-actuated detent adapted to embrace saidabutment to hold said lever when rctract ed,-an arm on said detent, and an abutment on the preceding drum of said series adapted to engage with-said arm to release said detent against the influence of its spring.
